8 Building the Business Case for SWM Funding Stormwater Management Funding & Program Review Studylate 2004 to 2009 Primary objective: To establish sustainable level of service for stormwater programs To propose a funding model that achieves the following criteria: fair and equitable reasonably easy to administer steady stream of funding for planning and scheduling system should be flexible enough to reward users who conserve runoff and reduce pollution.

9 Performance Benchmarking: National Water & Wastewater Benchmarking Initiative Stormwater Goal Model You can t improve what you don t measure

10 Determining Levels of Service & Activity Forecasting

11 Determining Levels of Service & Activity Forecasting

12 Why Define Level of Service? Communication of value for money buy in Legislative requirements and liability recognition Decision support to benchmark against established levels of service Recognition of Funding Gaps

13 Funding Gaps Approach to Stormwater Resiliency

14 Study Recommendations Level of Service Sustainable Level of Service $4,496,000 $6.5M (2012$) 4 yr Average Level of Service $2,412,429 Implement a Stormwater Utility

15 Benefits of Moving to a Utility Structure Dedicated funding source that allows for sustainability, flexibility and adaptability to respond to issues such as climate change Based on the user s amount of runoff contribution as opposed to property value Includes all contributors to the stormwater system Potential incentive to reduce stormwater runoff and pollutant discharge (i.e. installation of green roofs, rain barrels, etc.) Creates awareness of stormwater and importance of managing stormwater

16 Stormwater Utility Rate Schedule

17 Why a credit program? Customers/Residents Incentives to implement on site controls Financial benefit to properties with reduced impact = fairness & equity in rate model City of Waterloo Reduced contributions of runoff and pollutant loading Supports the City s stormwater management policies and water quality initiatives Provides potential future cost savings & benefits Natural Environment Improved water quality and runoff management = less erosion & better aquatic habitat Greater resiliency to adjust to climate change impacts

18 Stormwater Credit Program Benefits Demonstrate cost/benefit of implementing a stormwater credit program Two components: Identify ecosystem services & ancillary economic benefits Quantify potential direct program cost savings

19 Stormwater Credit Program Cost Benefits Ecosystem Services & Economic Benefits Pollution Abatement Reduced Flooding & Property Damage Groundwater Recharge Climate Change Adaptation Other property value, air quality & associated health effects, etc.

20 Potential SWM Program Savings Assumed sustainable funding level of $6.5M Focused on program elements influenced by credit program (fixed vs. variable cost analysis) Privately owned impervious surface (60%) vs. right of way impervious surfaces (40%) Potential savings of $1.9M annually

21 Stormwater Credit Program Launched January Provides financial incentives to all property owners who have implemented best management practices Residential and Non residential categories Key objectives include reducing the impact on the existing system, reduced pollutant loading, less erosion, potential long term cost savings

22 Stormwater Credit Program Non Residential & Multiresidential credits Credit based on: Flood Prevention 25% Pollution Reduction 15% Education 5% Residential credits Credit based on volume of water captured (5 tiers) Maximum credit value = 45%

24 Credit Program Approach Participation to Stormwater Resiliency

25 Credit Program Metrics Projected to receive applications in 1 st year Equates to 796,000 litres potentially diverted per rain event, 22,232,000 litres per year 22% uptake after the program launch 99.5% compliance, as per spot check program

26 Complimentary program aimed to provide community outreach Intended to link citizens with stormwater & landscape professionals Modelled after other successful programs using CBSM Made possible through funding from MOE Showcasing Water Innovation Fund
